I have kt7a-raid board. I have cd rom as master on ide1,a cd burner as master on ide2, hard drive as master on ide 3. I have, for boot sequence order, the bios set for first, second, and third boot device to be ata100raid. My hard drive is showing in system properties as scsi disk device. The option to enable disk write caching is checked, but grayed out. Is this a problem and is there a better way for me to set up my bios. I have only one hd.
